DESCRIPTION OF THE INVENTION OF THE CURRENT EMBODIMENT It will then be pointed out at the outset that in the following description of a presently proposed embodiment, which exhibits the significant features associated with the invention and which is clarified by the drawings shown in the following drawings, had chosen terms and a special terminology for the purpose of clarifying the idea of the invention in the first place.

In this context, however, it should be borne in mind that the terms chosen here should not be construed as limiting only to the terms used and chosen here, but it should be understood that each term thus chosen should be interpreted so that it additionally encompasses all technical equivalents that operate on the same or substantially the same way in order to be able to achieve the same or substantially the same intention and / or technical effect.

With reference to Figure 1, there is schematically shown the basic preconditions for the present invention and where the significant properties associated with the invention have generally been concretized, through an embodiment now proposed and described in more detail below.

Thus, figure 1 shows a holding unit 10 belonging to a crane arrangement and this holding unit 10 is adapted to be able to support a seat 11 intended for an operator of the crane arrangement 1. fixed but easily removably connected to a crane arrangement assigned post 1c, wherein the lower end portion 1d of said post 1c is in a known manner in a rotatable cooperation via a vertical axis of rotation with a foundation 1e.

A horizontal line of rotation between the lower end portion 1d of the post 1c and the foundation 1e has been assigned the reference numeral 1f.

A post-associated attachment point 10a, for said holding unit 10, is oriented adjacent to said lower end portion 1d.

Said holding unit 10 is arranged to have said seat 11 and an operating seat 30 belonging to the seat supported in its upper end portion 10b.

Figure 1 illustrates that the seat 11, via the shape and structure of the holder unit 10, assumes a position at a distance from the upper part 1c 'of the post 1c.

With reference to the clock 2 it appears that the holder unit 10 comprises two arm portions 10c, 10c ', one on each side of the post 1c, and that this holder unit 10 thereby forms a separate unit, which essentially consists of two straight arm portions.

The arm portions 10c and 10c 'are in a co-operation with each other primarily via a center-oriented intermediate piece 10d, but can also be joined via a connecting piece 10e connecting the upper end portions 10b.

The center-oriented adapter 10d is adapted to support one or more valve units 12, which are obscured by the post 1c in Figure 2 but slightly indicated in Figure 1.

The connecting piece 10e is included as part of, or is adapted to hold via a means, a seat 11 for the operator.

The post-associated attachment point 10a is in the form of a clamping joint.

A bolt connection associated with the clamping connection may be adapted to extend under a post-associated bracket "B1" (see figure 1) for a hydraulic piston-cylinder arrangement. upper end portion 10b by holding means not shown in more detail, such as a two-part connector.

Thus, with reference to Fig. 3, there is shown a crane arrangement-associated operating place 30 in side view and in Fig. 4 said operating place is shown in a perspective view.

The operating seat 30 comprises a seat 11 in the form of a chair seat 31 intended for an operator with a connecting backrest 32.

With a reference to the figures, it appears that the complete operating position with the seat 11 essentially consists of two endless pipe constructions 35 and 37.

The first, or upper, pipe construction 35 consists of an endless and in several respects curved pipe section, which in the following will mentally be divided into individual pipe sections for a simpler understanding.

The second, or lower, pipe construction 37 also consists of an endless and in several respects curved pipe section, which in the following will mentally be divided into individual pipe sections for a simpler understanding.

It is obvious that the different pipe sections merge into each other without joints.

Furthermore, a number of control levers 40, 41, easily accessible to the operator's hands, are provided in order to be able to actuate via them one or more valve units 12, part of a hydraulic system for actuating and maneuvering one or more piston-cylinder arrangements, included in said crane arrangements to e.g. maneuver crane arrangement associated arms.

The present invention thereby provides that said chair seat 31 and said backrest 32 are partially enclosed by a tubular structure, hereinafter referred to as an upper tubular structure or a first tubular structure. Figures 15 and 4 show with all the desired clarity that the first pipe construction 35 consists of a number of straight portions and arcuate portions connected to an endless shape, but this division into portions is only intended for to clarify the features of the invention.

A guardrail 33 consists of an upper tube portion 35a, formed as one with the legs 35b, 35c diverging from the back portion 32 and extending past and over the seat 31.

The legs 35b resp. 35c free end portions 35b 'resp. 35c 'cooperates with each short, downwardly directed, pipe section 35d resp. 35e and that these portions 35d resp. 35e are oriented outside and adjacent to said control lever or control levers 40, 41.

Mentioned short, downwardly directed, pipe sections 35d resp. 35e cooperates with a lower tube portion 35f, formed as one with the legs 35g resp. 35h converging towards the back portion 32 and running below and close to the side of the seat 31.

The upper portion 35a has a back part portion 35i formed against a partially circular line, to which the diverging legs 35b, 35c connect.

The lower portion 35f has a straight shaped dorsal part portion 35j, against which the converging legs 35g resp. 35h connects.

Said lower pipe portion belonging to the legs 35g resp. 35h, the seat seat 31 supports and a pivot shaft 36 is oriented below the seat seat 31, in order to be able to rotate said lower tube portion 35f and said tube structure 35 relative to an underlying tube structure 37.

The divergence angle "a" is here selected to be between 50 and 70 °, such as about 60 °.

More specifically, it is indicated that said tube portions 35e and 35f are oriented obliquely in relation to each other and with a larger distance between the portions oriented adjacent the backrest 32. The angular value "b" is chosen to be between 10 and 40 °, such as about 20 - 30 °.

The underlying pipe construction 37 has special fasteners to a holding unit 10 and / or to one or more foot-adapted support surfaces 37a and 17, respectively. 37b.

The underlying pipe structure 37 has a horizontally oriented pipe section or pipe section 37c and from this upwardly directed converging pipe sections 37d resp. 37e, with an angle "c" between the horizontally oriented pipe section 37c and said converging pipe sections 37d resp. 37e selected to be between 100 and 130 °, such as about 110 - 120 °.

The horizontally oriented pipe section 37c has the shape of two, "U" shaped, sections 37f resp. 37g with adjacent legs coordinated via a section 37h, serving as an attachment to the upper part 10b of a holding unit 10.

More specifically, it appears that those with a “U” shaped pipe sections each carry their foot-adapted support surface 37a, 37b.

The invention is of course not limited to the embodiment given above as an example, but may undergo modifications within the scope of the inventive concept illustrated in the appended claims.

It is especially important to note that each displayed unit can be combined with any other displayed unit within the framework in order to be able to achieve the desired technical function.
